A healthy metabolism is when your body efficiently converts the food you eat into energy. It allows you to maintain a healthy weight, have good energy levels, and support overall bodily functions. When your metabolism is functioning optimally, you can effectively burn calories and maintain or build muscle. It's important to note that everyone's metabolism is unique, and factors like age, genetics, and lifestyle can influence its speed. However, by focusing on proper nutrition, regular exercise, and adequate rest, you can support a healthy metabolism.
